All four of Glass’s grandparents narrowly avoided the gas chambers in Auschwitz.

In his late teens and early twenties, his father, who had whole bookshelves of books on the Holocaust, spoke about the horrific period on a daily basis. Glass eventually had to tell him: “I can’t talk about this anymore.”

For his academic thesis and campaign, Glass reached out to other children and grandchildren of Holocaust survivors and discovered he wasn’t alone.

He told The Guardian that he was “privileged” to hear many stories from young people who “should now be able to live with joy” but their lives are “damaged and they weren’t even there.”

The granddaughter of one holocaust survivor from London told Glass that her grandmother would tell her she avoided starvation in the camps by digging up flower bulbs and sucking out nutrients.

The granddaughter later developed anorexia and believes it was related to the stories she used to hear when she was younger.
